An object of theinvention is to provide a means whereby an insertedcollar may be bonded to the metal wall of the container by solder whichis applied so as to be covered and protected from contact with the foodproducts in the container, and which is applied in such a way as not toinjure the lithographing on the outer face of'the container. In thedrawings which show by way of illustration one embodiment of theinvention:

Figure 1 is a vertical sectional view through the upper portion of thecontainer embody ing the improvements.

Figure 2 is a view through a portion 0 the container showing the ripstrip removed and the end lifted from the container.

Figure 3 is an outer face view of a portion of the reclosure ring. y

The invention is used for securing an inserted reclo-sure collar to thebody of the container. As shown in the drawings the container body isindicated at l, and one of the ends is indicated at 2; This end issecured to the body of a double seam 3. The body wall is provided withan in wardly projecting bead 4 and with score lines 5 and 6 which form arip strip 7. Located within the body of the container is an insertedreclosure collar 8 which is attached to the body of the container. Thereis also an inserted reclosure collar 9 attached to the end so collarsare preferably made from metal by' rolling or drawing the metal so as toprovide a smooth unbroken edge for the collar as dis tinguished from acut or torn edge. The collars formed in this way and arranged asflameter,

shown in the drawingsform no part {of the present invention, but areshown 'andf'described and claimed in my co-pending application465,742filed July 3,1930. The pres Kent invention is directedparticularlyv to means for securing this collar8 to the body of thecontainer. This collar when inserted in the body 'is directly above thebead 4, but

is not many way attached to the'bead. The

beadiserves as a support for preventing the collar from being forcedinto the container by-the pressure applied'to the outer edge 7 thereof.In the form of the invention shown in the drawings the collaris providedwith an inwardly projecting bead 10 which forms 'a recess 11 in theouter face of the collar. This recess preferably extends all the wayaround the collar. 1 Again as illustrated in the drawings the recess 11isprovided with a soft solder 112 which is located at spaced in"-tervals." The entire bead may be filled with oven raised to atemperature of about 250 F.-, v and this will cause the solder .to meltand adhere to theinner wall of the body of the This is a temperaturebelow the teniperat-ure that willinany way'aifect the lith- Iographingon the outer'face of the can." The soldenbeing placedibetweenthe outer faceof the collar and the inner face of the container iscovered by the collar so that food products within the container willnot come in contact with the solder. Asnoted, the "solder is apin thecontainer and placed against the'bead 4 in the body wallof thecontainer.

The

' plied to the collar, the collar is'then inserted. C 9'0 container bodyis then passed through an oven heated as stated, and this causes a bondof solder tobe formedbetweenthe collar and the innerymetal' wall of thecontainer body. The ends of the collar are preferably abutted so thatthe collarfis of uniform diand also of uniform thickness throughout. 1

While I have described the] collars as loo formed'by a rolling ordrawing of the metal, it will be understood that it may be formed inother ways without departing from the spiritof the invention as setforth in the appended claims; It will also be noted that the solder asshown is applied at spaced points in the recess. While this greatlysaves in the amount of solderused, it will be understood that the soldermay be applied in other ways,

the essential feature residing inthe placing of the solder between thecollar and the wall of the container andthe use of a solder Which u canbe melted to form the bond joining the collar to the bodywithoutinjuring the litho- Y graphing on theouter face of the container. 7' 7Having thus described the invention, what 7 .is claimed as newand'desired to be secured by Letters Patent, is V r v i lfAn easyopening container having score Y lines inthe body adjacent oneendthereof forming a rip strip, a reclosure collar dis- I posed withinsaid container body, said collar having an'inw'ardly projecting beadformed 1 therein adjacent its lower edge and providing j a recess on itsouter face, said recess having soft solder applied therein, whereby whenthe collaris inserted in the container bodyand 1 heat applied theretosaid solder will'form a 2.
